Application filed Jame -24, 919. Serial 110,212,89 2 p v p v Be it=knownthat I, JoHN zen of the United States, residing at Seattle, in thecounty of King. and State of 5 .iWashington,

5 mprovements in Vehicle-Springs, the following is a specification.

- This invention has reference generally to improvements in that classof inventions known'as spr ngs, braces and. equalizers have invented newand useful of which proved vehicle spring.

7 operatively.

.- I The present invention has for its primary aim and object to provideadevice of the above mentioned character wherein thef leaves of-thespring I are of an improved construction and: are designed so as .to'be"connected together in' such a,

manner as to obviate leaf binding andto revent squeaking etc., when theparts, are" in an assembled position. i

More rtic'ularl this invention em braces the provision of a device ofthe above men'tioned character wherein the fastening means for theleaves :at the centers thereof 'ployed in all of the. above describedviews, .to lndlcat'e corresponding parts.

Referring now, more particularly,fto' the is designed to embrace theenlarged central I portions of the leaves and to embrace the spacing orfiller blocks so as to prevent relative movement of the spring andfiller blocks and to also operatively connect'the spring to the axle.

It is a more specific object of the present invention to provide aspring of the above mentioned character wherein clips of. the

improved construction are employed for' V tlons 2 and have theircornersrecessed 1nslidably accommodating the ends of the leaves and foraccommodating and retaining spacing or filler blocks against.displacement, said clips acting in'conjunction with the hangers forinsuring of an effective connection between the spring and ,the vehiclechassis.

Among the'other aims and objects of this invention may be recited theprovision of a device of the characterdescribed with a. view tocompactness, and in which the number of parts are few, the constructionsimple,

the cost of production low and theefliciency hi h.

ther improvements and novel details in the construction and arrangementof the various parts of the apparatus will be brought out more in detailin the description to follow, which for a clear understanding of theinvention should be considered in connection with the accompanyingdrawings formview thereof.

for the urpose of illustrationa convenient and SfltlSfflCtOI'Y.embodiment of the invention, It is to belnbted in this connection ingapartthereof, and whereinis disclosed that minorchanges inftheconstruction and. arrangement of partsmay be made without ng from theprinciple' ofj operation Fig. 2is-a longitiidinal central sectional Fig.3is'atop leaves.

simllar charactersof reference are em accompanying drawings, there isprovided a plurality of leaves 1 having enlarged rectangular centralportions 2 while the side portions taper as at 8 toward the outer ends.

Substantially rectangular spacing or filler blocks 4 are now employedand are disposed transversely of the enlarged" central por- Fig. 7' is aperspective view: of the recessed portions 5- and 6 res ectively thereofare U-bolts 7 the intermediate portions 8 of which first embrace theaxle 9 while the upper ends are passed through openings in a rectangularretaining plate 10 and have the free threaded terminals en-' sideportions of the leaves in spaced relation with each other to obviatebinding and squeaking noises while weakening of the spring is obviateddue to the fact that-no openings are formed through the central portionthereof.

An ear19 is cast with and ,dependlng from the under surface of the base forapurpose that will presently appear. The small outer ends of the springsare slid between the flanges and arranged within the ad]a- 'cent clipWhile interposed between the springs are substantially rectangularfiller blocks 20'the side edges of which taper as at 21 toward the rearedge, said plates being inserted through the open top of the clip and ofcourse being arranged alternately with respectto the ends. ofthe'springs.

Subsequent to the arranging of the ends of the springs and the blocks inthe clip the a cover 18 is attached while the ends of the springs have aslight sliding movem ent yet the blocks 20 are prevented fromdisplacement owing to, the retaining flanges 16.

Hangers '22 arenow emplo'yed'and are pivotally suspended in opposedrelation from the chassis-23 of the vehicle by means of a v pintle 24and have their lower looped ends 25 pivotally connected on the oppositesides of the ear 19by means of another pintle 26, this arrangementserving to operatively connect the ends of'the spring to the vehiclechassis, as is apparent. It will also be seen that by the provision ofthis peculiar con- .st'ructionleaf binding as well assqueaking noises atthe ends of the leaves is prevented and moreover the leaves are notweakened since no openings are provided therethrough for fastening theends thereof together.

It is believed in view. of the foregoing description that a furtherdetailed description of the operation of the invention is entirelyunnecessary; Likewise .it is believed that the advantages of theinvention will be readily apparent.

As many changes couldfbe made in the above construction and manyapparently widely different embodiments of thisginvention could be madewithout departing from the scope thereof, it is intended that all'mattercontained in the above description or shown in the accompanying drawingsshall be interpreted 'as illustrative and not' in a limited sense.
